DEscRIPTIo.N
The
1335
Power
Supply
is
a high
performance
singte
output
DC
power
supply
for
industrial
and laboratory
use.
Performance
with
economy
have
successfully
been
combined
to
provide
a compact,
fully
solid
state
instrument.
The
output
is
continuously
variable
from
o to
32v
and
can
supply
3A
max,
and
can
be adjusted
continuously
throughout
the
output
range.
The
front
panel
CURRENT
control
can
be
used
to
establish
the
outfut
current
limit (overload
or
short
circuit).
When
the
supply
is
used
as
a
constant
voltage
source
the
VOLTAGE
controls
can
be
used
to
limit
the
output
voltage.
When
the
unit is
used
as
a constant
current
source,
CURRENT
controls
can
be used
to limit
the
output
current.The
unit will
automatically
cross
over from
constant
voltage
to
current
mode
and
vice-versa,
if
the
output
current
or voltage
exceeds
these
preset
limits.
Output
voltage
and
current
are
continuously
monitored
on
two
front
panel
meters.
The
load
terminals
are
provided
on the
front
panel.
Either
the
positive
or
negative
output
terminal
may
be
grounded
or the
power
supply
can
be
operated
floating
at up to
a maximum
of t3ooVDC
above
ground.
All
the
outputs
are floating
i.e.
neither
the
output
positive
terminal
nor
the
negative
terminal
(nor
any
point
within
the regulator
circuitry)
is
con-
nected
to
ground.
The
power
supply
is
designed
to
operate
in
ambient
temperature
of
up
to
40"C
and
full
output may
be drawn
continuously provided
free
air
circulation
is
allowed.
The
unit works
from
mains
supply
of 11SVAC,
47-63

LOAD
CONNEG-TIONS:
The load
should
be connected
to
the
power
supply
output
terminals
using
separate
pairs
of connecting
wires.
This
will
minimize
mutual
cou-
pling
effects
between
loads
and will
retain
full
advantage
of the
low
output impedance
of the
power
supply. Each
pair
of
conhecting
wires
should
be as
short as
possible
and twisted
or
shielded
to reduce
noise
pick
up.
(lf
a shielded
pair
is
used,
connect
one
end
of the
shield to
ground
at
power
supply and leave
the
other
end
unconnected).
Positive
or
negative
voltage
can
be obtained
from
this
supply
by
ground-
ing
either
one of the
output terminals
or one
end
of the load.
Always
use
two leads
to
connect load to
the
supply, regardless
of where
the
set
up
is
grounded.
This will
eliminate
any
possibility
of the
output
current
re-
turn
paths
through
the
power
source
ground
which
would
damage
the
line

This
supply can
also
be operated

above
ground,
if neither
output terminal
is
grounded.

Observance

GROUND
LOOPS
A
ground
loop is
a voltage
drop
on
a
ground
bus
caused
by
a
power
stage
output
entering
the
ground
bus
some
distance
away
from
the
power
supply
ground
binding
post.
This
small voltage
drop, though
only
milliVolts
or microVolts,
is
a
part
of
the
output
load.
lf
a
preamplifier
input
of circuit
ground
is
connected
to
a
portion
of this
ground
bus, feedback
and
oscillation
may
occur.
To
prevent
this
all output
stages
should
be
positioned
as close
as
possible
to
the
ground
terminal,
preamps
farther
away.
Many
audio lC's
have
separate
input
and
output
grounds
to
prevent
ground
loops.
Even
though
power
supplies
are tightly
regulated,
a
short length
of a
power
bus can
present
enough inductance
to
cause
linear
lC
oscillation
at
high
frequencies.
For
this reason,
effective
bypass
capacitors
are
needed
to
bypass the
power
buses. Place
these
capacitors
as
close as
possible
to the
power
supply
pins
of the
lC.
Ceramic
disc
(0.1
pF
)
work
well
and
should
be
placed
across
as
many
lCs
as
possible.
Do
not
use
electrolytic
or
paper
capacitors
because
they
have
high inductances
and
cease to
act
as bypasses
above
one
or two MHz.
Bypassing
is
required
with
digital lC's
also;
problems
such
as inability
to reset
or to
clear and false
triggering
can occur if
lc's
are not
properly
bypassed.
